Just now, Luigi said:

Hi Luigi
Could the error happen when the password includes an odd number of double-quotes in it ?

Another thought : Many times, within Run(), using chr(34) [which corresponds to the Ascii code of the double-quote] instead of the double-quote character itself (") makes it work in an easier way, so try to use them as much as you can within the Run command, instead of double-quotes. Those quotes & double-quotes are a real headache (especially when intermingled in a complex Run Command)

Here is an example where I use them :

Local $par1 = "1st par (variable)", $par2 = 2

$iPID = Run(@AutoItExe & " /AutoIt3ExecuteScript " & chr(34) & @ScriptDir & "\Run 1b.au3" & chr(34) & _
    " " & chr(34) & $par1 & chr(34) & _
    " " & $par2 & _
    " " & "3" & _
    " " & chr(34) & "4th par (string)" & chr(34))

which displays this in Run 1b.au3 :

Good luck

Thankyou @pixelsearch, I will try.

I unknow about chr(34)

pixelsearch's method works great. I tend to think it looks cleaner to use single quotes, but it's personal preference

Local $par1 = '1st par (variable)', $par2 = 2

$iPID = Run(@AutoItExe & ' /AutoIt3ExecuteScript "' & @ScriptDir & '\Run 1b.au3"' & _
    ' "' & $par1 & '"' & _
    ' '  & $par2 & _
    ' '  & '3'   & _
    ' "4th par (string)"')
